Now we see a three way race and possibly four if Samsung can get traction with its Tizen operating system that it’s bundling into the latest version of the Gear smartwatch.

One positive aspect of the four way battle is that three of the participants – Firefox, Tizen and Android are relatively open so compatibility between them isn’t impossible.

For Google and Apple though, this four way tussle presents a problem to their business plans.

Apple’s iOS ambitions of putting the software in smarthomes, connected cars and, possibly most lucratively of all, into retailing with iBeacon are threatened by a fragmented market and a rapidly eroding market share.

For Google, both Firefox and Tizen threaten the dominant position of their Android operating system that forms a plank in the company’s ambition to control the planet’s data and become an ‘identity service’.

It’s early days to forecast the demise of either Android or Apple iOS, which is unlikely in the short term, but if Firefox’s operating system does take hold it will mean the smartphone industry is about to become a lot more complex.
